Abstract

The invention provides a lighting unit comprising a first light source and a second light source, a first plate-like light guide having first light guide edge, and a second plate-like light guide having a second light guide edge, wherein the first light source is configured to couple first light source light into the first plate-like light guide via the first light guide edge, wherein the second light source is configured to couple second light source light into the second plate-like light guide via the second light guide edge, wherein the first plate- like light guide is configured to couple first lighting unit light out a first light guide face and wherein the second plate-like light guide is configured to couple second lighting unit light out via a second light guide outcoupling edge, wherein the first light source and the second light source are independently controllable.
